NICREW ClassicLED Plus LED Aquarium Light with Timer, 27 Watts, for 36 to 48 Inch Fish Tank Light, Daylight and Moonlight Cycle

Got this product 3 times now, theyre my most ideal lights for my plants and fish. I genuinely cant imagine my tanks with a different light, the timer feature is magnificent, the lighting is bright and adjustable. Theyre great for making your fish stand out especially if you have colorful fish. Ive dropped it once and it didnt break (thankfully) and i have spilled water on it by accident. Still works, very easy to use and place on your tank. The price makes it worth it.

Great value for a light that fits perfectly. I like that it can simulate the natural rise and setting of the sun. Super easy to install and use. No compaints!

The media could not be loaded. I did read reviews and got an idea of the features of the NICREW ClassicLED Plus. The 24” light fits perfectly to the 20 gallon. I use the 48” and a 24” on the 75 gallon.The NICREW ClassicLED has 2 timers. One for the white/red/green bulbs and the other for the blue lights. The easy to use wired control allows the user to control the brightness of each of the two banks independently. Also, each bank of LEDs have their own timer. For sunrise and sunset the timer can be set to increase and decrease on a 15 or 30 minute setting.The settings on my control allow the blue light to turn on at 6:30am and slowly increase to 68% intensity. It is a beautiful morning look as the guppies awake. At 8am the white/red/green bank turns on and increases gently to 33% intensity. At 7pm the white/red/green bank decreases in intensity and at 7:30pm the blue light decreases in intensity over the next 18 minutes. I have my sunrise/sunset timer on 30 minutes but the intensity is only 68% so it takes 18 minutes to get to zero intensity.The proportion that I have chosen in light intensity enhances the guppy’s colors while it still is promoting excellent plant growth. I do not use CO2 but I do use SeaChem Flourish and Flourish Advance. These lights are very bright. I have a 48” and a 24” on the 75 gallon because my floating plants are in the rear right corner of the aquarium and I don’t use the full glass tops.I wanted an LED that had intensity adjustment and was designed for aquarium plants. I am so pleased with the two separate timers and sunrise/sunset mode. The three separate units turn on/off simultaneously.. NICREW ClassicLED Plus is very versatile!

I purchased this light in April of 2022. It appears to be a new revision. While the manufacturer's pictures on Amazon seem to match the product I received, the item and pictures do NOT match most of the reviews I see posted about this light, so hopefully this will be educational about what is currently shipping. Also, it has been a while since I've kept an aquarium and only recently am I setting up a new tank. I've never used an LED aquarium light before.This light has an integrated, hardwired timer controller that can control 2 separate channels or modes - one for daytime(?) lighting and one for blue lights. The LED array consists of white, blue, green and red bulbs. In timer mode, you can set one time period to turn on and off the daytime lights and another period to control the blue lights. I'm not entirely sure why I want to control the blue lights separate from the rest. Perhaps as a night light? You can also set 0, 15, or 30 minutes to phase in and out the light intensity - like a sunrise and sunset. You can control the intensity of each mode in timer mode, from 0 to 100 percent. This is all great. You can also turn on the full light or the blue lights manually and then return back to your program.However, there are some quirks - maybe even flaws - with the current controller. First - if you lose power to the light, the time gets reset to 00:00. Your program is retained in memory, but until you reset the time, the light will run on an altered schedule. Second, you cannot dim the light in manual mode. It only works at 100%. If you want to skip using the timer and control the lights externally via a timer or smart plug, you only can run the lights at full blast through manual mode. If the power cuts out while lights are on manually, they do come back on when power is restored. Third, and I'm new to LED aquarium lights so this might not be a flaw, however, when the lights are turned on in manual mode - all four color LEDs are used. But, when the daytime mode is triggered via the timer, only the white, red and green lights are lit. The blue lights are off. Note you can overlap the time period settings for the two modes, so maybe it is by design to have separate blue light control and you just run the two programs concurrently to have full RBGW spectrum lighting.To me, the loss of the correct time due to a loss of power is a problem. One work around would be to run the light through a battery back up, preserving the time and light operation until your battery dies. Second, you CAN use an external timer or smart plug. To do this, program the modes to both run for the full 24hours - 00:00 - 23:59. Set your intensities and don't bother with sunrise/sunset. Run this through your timer. When power gets cut to the led lamp - due to external timer or power outage, the lights go out. When power is restored, the lights will come back on after about 10 seconds - the clock will be at 00:00. They will come on at the programmed intensities. Both options work. Option 1 depends on an external battery backup (separate purchase) but preserves the sunrise/sunset feature. Option two depends on a cheaper outlet timer or smart plug but loses sunrise/sunset and the ability to turn on the lights manually through the LED lamp - you can use your smart plug instead.The light didn't come with a manual. None was posted to the Nicrew website that matched the new revision either. But Nicrew support was responsive to email requests through their website. I received responses overnight. They were able to provide a manual and answer some questions I had. Nothing in the manual details WHY or WHEN I want to use the blue lights though. I do question the spectrum chart they show on the box - is this spectrum only when all 4 light colors are running at 100%?I have not used this light on a planted tank yet, so I can't comment on plant growth. Heck, I'm not even sure how I'm supposed to run it - RGW or RGBW. All that being said, looking at some other lights in the same price range, its pretty great that Nicrew is offering a programmable timer. There is certainly value here. Add in a battery backup for the clock (let the lights turn off in a power outtage) and this would be a certain winner. Letting me dim the lights in manual mode would be an extra nice touch. Maybe in revision 3.
